Step 8. After compilation has completed, type "make install". This will install Asterisk in your Scratchbox environment, under /tmp/ast121/

Step 9. Go to /tmp/ast121/usr/lib/asterisk/modules and do "rm -f *ilbc* *lpc* *sqlite* ; strip *.so". This will remove the ilbc and lpc10 codecs that are too processor intensive for the Nokia 770, the cdr_sqlite.so file and remove all symbols to make the files smaller. Also, go to /tmp/ast121/usr/sbin/ and do "strip asterisk" (I'm sure this could somehow be done directly at compilation time, but I don't know how yet). You can also take out the "mohmp3" folder from within /tmp/ast121/var/lib/asterisk/, it contains 4 large MP3 files used for music on hold (you can put them back if you figure out a way to play them on the 770).
